Blue white assay
WebBlue-White Selection / -Complementation During processes of genetic engineering, the so called Blue-White-Selection is used for evaluation of recombi-nant bacteria. Thus, it not only provides identification of those bacteria carrying the desired plasmid, but also helps to determine whether the recombination procedure has proceeded correctly. WebThis experiment provides a DNA fragment together with a linear plasmid and T4 DNA Ligase. Following the ligation to synthesize the recombinant plasmid, competent E. coli cells are transformed and the number of …

The blue–white screen is a screening technique that allows for the rapid and convenient detection of recombinant bacteria in vector-based molecular cloning experiments. This method of screening is usually performed using a suitable bacterial strain, but other organisms such as yeast may also be used. DNA of transformation is ligated into a vector. The vector is then inserted into a compet… WebIn some blue/white screening systems, an additional reagent must be used: IPTG (isopropylthiogalactoside). IPTG is an inducer that de-represses lacZ expression (it turns the gene on). In some cases, without IPTG, not enough β-galactosidase is produced to turn the colony blue even if the lacZ gene is intact.
